NWS Medford, OR wrote its last area forecast discussion before the first event at Apr 10, 7:57 AM PST, 3 hours 18 minutes earlier.
Area Forecast Discussion National Weather Service Medford OR 857 AM PDT Wed Apr 10 2019 .DISCUSSION...The latest visible image shows mostly clear skies east of the Cascades, northern California and portions of the west side valleys south of the umpqua Divide. Low clouds are lingering in some the valleys near Grants Pass, Umpqua Basin and also some are banked up along the Siskiyous and Cascades. The lower clouds should burn off later this morning. At the same time, high clouds are already moving in from the north and this will eventually thicken this afternoon. Radar is not showing any returns and have not seen any reports of precipitation, so this was removed for this morning. This afternoon, the general consensus shows the best chance for precipitation to remain north of the Umpqua Divide and moreso in northern and eastern Douglas County and Coos County. So have made adjustments to the forecast to reflect this thinking. Precipitation chances increase tonight, especially along and west of the Cascades as a front drops south into our area with the upper flow from the northwest. Please see previous forecast for more details on the weather for this time period and beyond. -Petrucelli && .AVIATION...For the 10/12Z TAFS...Overall, expect a mix of MVFR/VFR with terrain obscuration with MVFR becoming more widespread overnight since there'll be plenty of low-level moisture due to recent rainfall. These ceilings will last through Wednesday morning. Some IFR is also possible, but confidence is low in timing and extent of these lower conditions. Some improvement is expected during the late morning and afternoon, but showers and lower flight conditions are likely to return in the evening and overnight as the system approaches the area. -BPN/BR-y && .MARINE...Updated 800 AM PDT Wednesday 10 April 2019...High pressure over the waters will weaken tonight, and a front will move through the area Thursday. High pressure will rebuild Thursday night into Friday, then weaken again Friday night. West to northwest swell will build to near or just above 10 feet Friday and remain elevated into the weekend. Another front will move onshore Saturday, followed by a weaker front Sunday. Yet another weak front will move through Monday night. && .PREV DISCUSSION... /Issued 308 AM PDT Wed Apr 10 2019/ DISCUSSION...Current satellite imagery is showing some clouds overhead, but concurrent +0.5 degrees RADAR is showing no returns as of 2:30 AM. That being said, the -0.2 degree radar are showing some light returns spilling across the Umpqua Divide from north to south and in the Cascades. Web cameras are showing some snow at the Willamette Valley Pass on Highway 58, and on Dead Indian Memorial Road. Siskiyou Summit appears to have ongoing rain, but it is difficult to tell with that web camera. These showers will continue through the night, so travelers should prepare for potential slippery conditions if traveling in the mountains, otherwise, things remain quiet. A few flooding concerns remain in the area, mainly the Coquille River at Coquille which continues to threaten homes and roads in low-lying areas near the river from the estuary to Myrtle Point. The Coquille is still in Moderate Flood Stage, and has remained near crest for the last 30 hours or so. Flooding impacts from this river will remain for a few more days before the river returns to its banks. Please see the FLSMFR for more information. Meanwhile, the Pit River at Canby and the Sprague River at Beatty remain near or at bank full, and are continuing to rise. Both rivers are not expected to reach flood stage, but they will be close. So will allow the flood watches to continue. Please see the FFAMFR for more details. The next system will arrive at the Pacific Northwest Coast today, but looks to remain north of southern Oregon. This means that the majority of precipitation will occur north of our area, but the Coastal Range and the Southern Oregon Cascades north of the Umpqua Divide could see a little bit of precipitation today. This system will spread southward on Thursday, but only light rain is expected, with maybe some moderate rain occurring at the coast near Coos Bay and Florence. Showers will continue overnight Thursday and taper off on Friday. Snow levels will be around 4000 to 5000 feet through this entire system. Thus, the precipitation associated with this system is not expected to be enough to increase flooding along the Coquille or any of the other rivers, but it may delay the receding of the rivers at least a little bit. Meanwhile, the snowfall in the Cascades will be between 5 and 9 inches, with the highest amounts occurring over the highest elevations (think Crater Lake). Interstate 5 at Siskiyou Summit may see a dusting of snow, but the higher passes could be the issue. Regardless, this snow will fall over a long enough time period that it should remain below advisory amounts. Friday will have a quick break in the action before the next system arrives on Saturday. Models are suggesting that this system will arrive in the late morning to early afternoon for Douglas County and northern Coos County, spreading into the rest of southern Oregon and northern California Saturday evening and night. The showers continue on Sunday as a shortwave reinforces precipitation chances. Ensemble guidance suggests that this system won't be as exciting as the last weekend, despite some decent winds aloft. Precipitation chances remain somewhat elevated through the rest of the forecast period, but some of the models are trying to suggest a ridge of high pressure trying to build in with systems moving north of the ridge. Have gone with the ensemble guidance here as picking a deterministic solution here would be strange (the GFS is strong with the ridge with precipitation remaining north of Eugene, the ECMWF is a bit weaker with the ridge allowing precipitation to reach the northern reaches of the Umpqua Divide, and the Canadian is very weak with the ridge allowing precipitation to reach the entire area). Regardless, expect this to get ironed out in future runs; so it's worth keeping an eye on. -Schaaf AVIATION...For the 10/06Z TAFS...Overall, expect a mix of MVFR/VFR with terrain obscuration with MVFR becoming more widespread overnight since there'll be plenty of low-level moisture due to recent rainfall. These ceilings will last through Wednesday morning. Some IFR is also possible, but confidence is low in timing and extent of these lower conditions. -Spilde/BR-y MARINE...Updated 200 AM PDT Wednesday, 10 April 2019...Swell dominated seas will ease today with mostly light to moderate north to northwest winds. A frontal system will push through the area Wednesday night into Thursday with some showers, but winds and seas should remain below advisory levels. West-northwest swell will build to near or just above 10 feet Friday and remain elevated into this weekend. The next front will move through Saturday or Saturday night. Models have trended weaker with another front expected to move in early next week. -Spilde/BR-y && .MFR WATCHES/WARNINGS/ADVISORIES... OR...None. CA...None. Pacific Coastal Waters...None.
